PHILADELPHIA (AP) — Andrew Bynum's anticipated Philadelphia 76ers' debut is on hold.
One day before training camp was set to open, the Sixers announced Monday they would shut down their new franchise All-Star for three weeks as a precaution after he received knee treatment in Germany.
Bynum was grounded before his first practice in the No. 33 jersey.
"I'm going to do everything in my power to get back," Bynum said.
Bynum had injections of plasma-rich platelets that supposedly stimulate healing in arthritis-affected areas in both of his knees. The Sixers said last week he was cleared to play in camp. Bynum felt some discomfort late last week and, after meeting with doctors in New York and Philadelphia, the Sixers made the call to bench him. The Sixers wanted to give him enough time to have the treatments take hold in the knee.
The team said Bynum also had a bone bruise on his right knee. Bynum said the bone bruise was unrelated to the knee treatments.
Bynum came to Philadelphia with an oversized warning label on his achy knees. He's been plagued by problems in the past, one reason he sought out the same treatment — called Orthokine — in Germany used by former Los Angeles teammate Kobe Bryant and New York Yankees third baseman Alex Rodriguez.
Bynum said this current knee ailment isn't as bad as the issues that have dogged him in the past. He reported no swelling in his knees.
"I feel a lot better," he said. "The Orthokine is definitely working."
Bynum, 7-foot and 285 pounds, said doctors advised he have the knee treatment closer to the season for maximum effectiveness. Bynum said he had the injections during the third week in September. He will continue to participate in low-impact conditioning drills.
The Sixers open the regular season Oct. 31. Bynum would have about a week between his scheduled return and the opener.
"At this point, I just need to go out and work on my craft," Bynum said. "I should still be able to do that, even with being shut down."
The injury throws an unwanted wrinkle into the start of coach Doug Collins' third season. Collins led the Sixers to the playoffs each of the last two seasons and was rewarded Monday when the team picked up the option on his contract for the 2013-14 season.
Collins said he wants to remain with the organization in some capacity when his coaching career is over.
He said Bynum was "incredibly down" about not being able to play.
"He is so champing at the bit to come in here and live up to all the expectations that have been placed on his shoulders," Collins said. "He knows what's at stake."
